-*Sgarbossa Criteria help in assessing the likelihood that a patient with chest pain and a baseline LBBB is having a STEMI
+==Criteria==
-*Low Sensitivity, High Specificity
-==Sgarbossa Criteria==
+*ST elevation ≥1 mm in a lead with upward (concordant) QRS complex - 5 points
+*ST depression ≥1 mm in lead V1, V2, or V3 - 3 points
-*ST-segment elevation ≥1 mm in a lead with upward (concordant) QRS complex (5 points)
+*ST elevation ≥5 mm in a lead with downward (discordant) QRS complex - 2 points
-*ST-segment depression ≥1 mm in lead V1, V2, or V3 (3 points)
-*ST-segment elevation ≥5 mm in a lead with downward (discordant) QRS complex (2 points)
-Points	Probability STEMI
+==Points==
-	16%
+*≥3 points = 98% probability of STEMI
--10	88-100%
-==Notes==
-*Unlike general AHA STEMI criteria, the Sgarbossa criteria do NOT need to be found in contiguous leads
-*RBBB should NEVER have ST elevation
